OK, that works, but I would really like to do
the following:
PREFIX property: <http://dbpedia.org/property/>
SELECT ?x ?abstract
WHERE
{
?x property:abstract ?abstract.
FILTER regex(?abstract, "(?i)engine"@en).
}
so I could get all references for "engine"
such as "jet engine"
"steam engine"
"rocket engine"
"search engine"
but when I try the above I get a 500 error???

Hi John,
Try "Jet engine"@en. The literal has an RDF language tag to indicate
that it's the English label.
Best,
Richard
